Me too. I like both the airline and DXB airport, and I like that they refunded my ticket within hours when flights were suspended between Dubai and Dammam because of COVID. That was in July last year. Gulfair also refunded, but took their time. Malaysia were also quick.
Looking at the post you pasted, different sections of āeconomyā are priced differently on different days. Emirates do not guarantee you can just switch your ticket without paying more. They guarantee there will be no charge just for changing. Re this thread - the author does not explain why they are unhappy with Oman Air, so who knows.
Did I say there were no buses from the Southern Terminal? No. And I specifically mentioned that there were buses from the airport. You know, that part where I say āthere are buses from the airportā? Doubtless the person asking the question will be delighted you have a car. Bye now. š
In my early days in BKK I booked a trip to Samui starting from my hotel. After being picked up in a mini bus I was surprised half an hour later when the five of us were transferred to a pick up truck. After another 45 minutes I noticed we were passing the hotel Iād been staying at. Donāt book trips at your hotel. Find out where the bus leaves from and buy a ticket there. For Hua Hin it will probably be the Northern bus terminal near Pinklao, or the bus from the airport.
